    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      		Condition
      		Specified Condition
      1 - 2
      		20°C (68°F)
      		11.6 to 12.4 Ω
      If the result is not as specified, replace the injector assembly.


  1. Check the operation.

    CAUTION:
    Perform the inspection in a well-ventilated area.
    Do not perform the inspection near any open flames.

    3. Connect SST (adapter and hose) to the injector, and hold the injector and union with SST (clamp).

    4. Put the injector into a graduated cylinder.

      CAUTION:
      Install a suitable vinyl tube onto the injector assembly to prevent gasoline splashes.

    5. Operate the fuel pump (YARIS_NCP93 RM000000SXS05AX.html).

      Difference between each injector:
      11 cm3 (0.7 cu in.) or less
      CAUTION:
      Always do the switching at the battery side.
      If the injection volume is not as specified, replace the injector assembly.

  1. Check for leaks.

    1. In the condition above, disconnect the test probes of SST (wire) from the battery and check if the fuel leaks from the injector.

      Fuel Drop:
      1 drop or less every 12 minutes
